Permission "artifactregistry.repositories.downloadArtifacts" denied on resource

While the artifact repository was successfully creating, running a docker push to push the image to the google artifact registry fails with a permissions error even after granting all artifact permissions to the accounting I am using on gcloud cli.

Command used to push image:

docker push us-central1-docker.pkg.dev/project-id/repo-name:v2

Error message:

The push refers to repository [us-central1-docker.pkg.dev/project-id/repo-name]

I was able to recreate your use case. This happens when you are trying to push an image on a repository in which its specific hostname (associated with it's repository location) is not yet added to the credential helper configuration for authentication. You may refer to this Setting up authentication for Docker as also provided by @DazWilkin in the comments for more details.

In my example, I was trying to push an image on a repository that has a location of us-east1 and got the same error since it is not yet added to the credential helper configuration.

And after I ran the authentication using below command (specifically for us-east1 since it is the location of my repository), the image was successfully pushed:

gcloud auth configure-docker us-east1-docker.pkg.dev

QUICK TIP: You may get your authentication command specific for your repository when you open your desired repository in the console, and then click on the SETUP INSTRUCTIONS.
